Abstract Sorghum (Sorghum bicolor (L.)) is one of the potential commodities that can be developed to support food and energy diversification programs in Indonesia. It has the advantage that one of them can be ratoon. However, the yield of ratoon is lower than that of the main crop. The research on ratoon sorghum was carried out in vertisol soil. This aims of the study to determine the interaction between biochar application and number of shoots on the growth of ratoon sorghum in vertisol soil, to obtain the right dose of biochar and to get the appropriate number of shoots to increase the yield of ratoon sorghum. The study was arranged in a factorial manner using a Completely Randomized Block Design (CRBD). The treatment factors were biochar (without biochar, 2.5 tons/ha, 5 tons/ha and 7.5 tons/ha), and the number of shoots (1 shoot, 2 shoots, 3 shoots, and 4 shoots) at the 5% level. The results showed that there was no interaction between biochar treatment and the number of shoots on the variable of panicle sorghum, weight of fresh stover, and weight of dry stover. The results showed an interaction on the variable of plants height observation. Provides growth results that are not significantly different in the parameters of plant height, panicle length and panicle weight. Gives significantly different results on panicle length, weight of fresh stover, and weight of dry stover. The number of 1 shoots produced the highest growth for all observed variables.

The number of seedlings per hill of rice plants affects the level of productivity , the use of seeds per hill with the right amount of rice production. This research aims to determine the effect of the number of seeds/clump on the growth and production of rice. Research using randomized block design (RBD) consists of five treatments with four replications. The treatments tested were: A (1 seedling/hill), B (3 seedling/hill), C (5 seedling/hill), D (7 seedling/hill), and E (9 seedling/hill). The seeds used are Batang Piaman variety, 25x25 cm spacing. The experiment sites in lowland farmers Lubuk Minturun Sungai Lareh village, Koto Tangah district, Padang city, West Sumatra province on wed season 2009/2010. Fertilizer is given as 150 kg Urea, 100 kg SP36 and 75 kg KCl per hectare. Urea and KCl are given three times, with brocasting system at 7, 28, and 45 Days After Planting (DAP), while the SP36 is given at 7 DAP combined with Urea and KCl. The results showed the treatment number of seedlings provide significant effect (P<0.05) on the number of grains per panicle and grain yield. However, no significantly effect (P<0.05) on plant height, maximum number of tillers, number of productive tillers, panicle length, percentage of empty grains, and weight of 1000 grains. The use number of seedlings less than five seedling per hill produces the high number of seeds per panicle and grain yield per hectare. Based on these results it can be concluded that the number of seed on the rice crops are not more than five seedling per hill. Keywords: efficiency , number of seeds , production, lowland rice.
